5.0 out of 5 stars Highly recommended for those fasting!

K. · 25 April 2021

I love these hydration tablets - they've been my saviour since starting intermittent fasting (16/8) 6 weeks ago. My first week of fasting made me feel lethargic with headaches every night during my fast. I also felt hungry and couldn't sleep. I almost gave up fasting until I read about electrolytes, so I purchased these. I've been taking two to three tablets daily, depending on how I feel. I have a Tropical or Berry flavoured tablet dissolved in water to use during 20 to 30-mile Zwift rides/races. During the night (when fasting and feeling hungry), I break up a Berry flavoured tablet to suck on - it tastes great and is similar to Barrat Refreshers. I found that Tropical is the best flavour to use in water followed closely by Strawberry & Kiwi. These two flavours taste too artificial to suck on. Berry is fine in water but improves with a dash of no added sugar berry flavoured squash.These tablets have boosted my performance on the bike (I no longer drink sugary Lucozade) and have irradicated headaches, lethargy and hunger pangs before bed.I'm starting my 7th week of fasting and 15lbs down with another 15-20lbs to go. I've struggled with weight for the past 20 years and tried every diet going. Fasting is the only diet (or I should call it a lifestyle) that works, and these tablets are a must for this new way of life.Update (6th June 2021): I've now lost 25lbs (11.3kg) since 14th March, and that includes a recent weeks holiday filled with plenty of beer and food (with desserts). I can't quite believe how fasting has transformed my body, and these tabs have been a key part of this process. ​I've gone from XL t-shirts to Medium and have never been happier! I plan to have a six-pack by August. :)Update (24th September 2021): I've lost 35lbs (2.5 stone), reaching my goal weight back in mid-August. I'm now working on body recomposition to get more definition with weight training, less cardio, more protein (supplementing with Myprotein Impact Whey Protein shakes), and lowering carbs (but not cutting them out). I just had a big bowl of lasagne with garlic bread :). I'm still fasting roughly 16 hours (between 8 pm and 12 pm) as it's a way of life for me, and I still use these tabs daily for exercise and fasting. I eat two meals a day with the occasional sweet treat and a few beers down the pub. I have never tracked food intake from day one but have a good understanding of nutrition and macronutrients. I used to eat a big bowl of porridge for breakfast, but now I have a big 4-egg omelette stuffed with ham, mushroom, and cheese with half a tin of baked beans. I'm no longer weighing myself daily since reaching my goal weight but keep myself in check with the trusty tape measure.

5.0 out of 5 stars Good taste, not too sweet

I use these daily for my ileostomy, they have a good taste and aren’t too sweet or too strong, unlike others I’ve tried.They’re a good quality, and are very effective as have helped with dehydration from kidney issues. They dissolve easily, I like to add some warm water to mine to speed it up.

4.0 out of 5 stars Good hydration support with a light flavour and no sugar

I’ve been using the HIGH5 ZERO Tropical hydration tablets during workouts and they’re great for staying refreshed. They dissolve quickly in water and taste light and fruity without being too sweet. I like that they’re sugar-free and have zero calories, yet still help with recovery thanks to the electrolytes and vitamin C.They help reduce fatigue during longer sessions, though heavy sweaters might feel they need a bit more sodium. The tablets work well for general training and everyday hydration.Overall I’m happy with these and they make a good addition to my fitness kit. I’d recommend them if you want a clean, refreshing way to hydrate.

After days of searching for electrolyte tablets, I finally boght these for myself and misses. We were not disappointed to say the least. Absolutely brilliant!* Easy to desolve in water in a matter of minute or two.* If you are someone who sweat a lot or feel low then these are definitely for you.* Great taste and sugar free.* We definitely felt more energy after using these to carry on with our day.* These have helped me focus more even after a long day at work and gym.* You feel the energy and strength to continue with your day without feeling tired, sleepy or sluggish.* These come in many different tastes so you can choose the taste your like best or experiment with different tastes to find the one you love the most:).Well worth the money:)

5.0 out of 5 stars Works well and improves hydration with the urge to drink loads of water.

Very good. I only have the citrus tablets. Usually 1 or 2 in 1/2 a litre of water. Tastes ok like a lemomy drink and the electrolytes really do work.I've noticed at the climbing gym that I feel much more hydrated without the urge to drink loads or water. I usually drink an hour before the gym and then during the work outs. It really works. Would recommend trying it.

These electrolyte tablets have been a game-changer! The berry flavour is refreshing, they dissolve perfectly with no chalky residue, and the handy tube makes them easy to carry in my bag. I’m drinking so much more water, feel so much better, and have even lost 22lbs since switching from sugary drinks. Highly recommend!I’ve been using these electrolyte tablets for a few months now, and they’ve honestly been life-changing. Before, I wasn’t drinking enough water and was constantly tired, dizzy, faint, and battling headaches. Since using these, I’m drinking so much more water and feeling so much better!The berry flavour is my favourite – it’s refreshing, not overpowering, and just the right amount of taste when used as recommended (1 tablet per 750ml of water). They are so easy to use and dissolve very quickly with no chalky residue, unlike other brands i have used that disolve poorly and stay lumpy. These leave perfectly clear, great-tasting water, be it refrigerated or at room temperature, the taste is yummy.I love them so much I’ve set up a subscription so I never run out. A nice bonus is that by drinking more water (and cutting out sugary drinks) I’ve also lost 22lbs – which feels amazing!The only “downside” is that now I’m properly hydrated, I’m in the toilet a lot peeing more often 😂 but that’s a small price to pay for how much better I feel.Highly recommend for anyone who struggles with hydration – these have made water enjoyable again!
